Separations using mass transfer equipment are solved using Aspen Plus. Possible thermodynamic choices are reviewed. One multicomponent distillation column is modeled using a shortcut method (DSTWU), and the same column is modeled using a more realistic method (RadFrac) with plate-to-plate calculations. A series of distillation towers is modeled to separate a multicomponent mixture into its component parts. A packed bed absorption problem is solved.
